Stuttgart-based exhaust specialist Eisenmann GmbH has created a stainless steel system for Porsche’s 911 Speedster model.

The bulk of the company’s work is providing OEM units for manufacturers such as Porsche and AMG, so Rolf Eisenmann and his team always look forward to one-off projects such as this. The owner of this particular Porsche 911 Speedster loved the way it looked and performed, but felt that sound of the car just didn’t match its persona.

The engineers at Eisenmann went on to completely redesign the internals of the factory exhaust system, improving its tone and personality, while adding in valve control to allow adjustment of the car’s level of civility.
